I may be reading the code wrong. But doesn't Control::Handle return the client handle?
At least it looks like it is initialized with the client handle. Control returns NativeWindow::Handle. The native window's handle is set by a call to CreateHandle. This sets the handle value equal to the value returned by XplatUI.CreateWindow. CreateWindow returns Hwnd::Handle, which is initialized with the client window. Look at the setter of Hwnd::ClientWindow.

Yes, the handle that is returned by Control::Handle is of no use for using with cairo. There's usually a window right on top of the one this handle describes. As I already answered before, to draw on our MWF windows, for best resultsSystem.Drawing should be used. We have no 'safety' locks and such to deal with someone outside of MWF drawing on our windows alongside us. If you try to own the whole window and do not expect MWF to draw, you'd need to set the appropriate styles on Control (AllPaintingInWmPaint and UserPaint), and get the Hwnd.Client handle via reflection to have the proper window do muck with.
